Engine air compressor leaking air around relief valve

[tankcj]

Anyone ever have air leaking around the relief valve on their engine air compressor? It doesn't appear to be leaking from the port itself but instead is leaking from the side. I'm wondering if I just have a blown O-ring on the relief valve.

Do you think you are talking about the Governor?

Lol! Maybe?... I’m not sure...it’s on top of the actual air compressor right near the air line. I definitely ID’d the part (P/N 225-5222). Cat calls it a “VALVE AS”.

This is the part in a slightly different location on a C7 air compressor. I have a C9s.

Looks like a pressure relief valve!
